PATENT OFICE.

QWILLAM n. nur, or READING, -PENNsYLvANrA- TRAY.

Be it known that I, WILLIAM H. RAPP, a 4citizen of the United States, and a resident of the cit of Reading, in the county of Berks andv tate of Pennsylvania, have invented certain new and useful Improvements in Trays, of which the following is a specification. My invention relates particularly to trays adapted to beconvenient-ly piled or stacked one upon another, and employed for various purposes such for instance as the manufacture of cenfections; and it consists essentially in the improved corner-construction provided for, as hereinafter fully described in connection with the accompanying drawings and specifically pointed vout in the claims.

Figure 1 is a perspective view of ay tray embodying my invention. Fig. 2 is an enlarged cross-sectional view taken on the line 2 2 of Fig. 1, indicating .also the manner of stacking the trays one upon another. ,Fig 3 is a cross-sectional view on the diagonal line 3-3 of Fig. 1, showing the sealing material in the corner thereof. Fig. 4 is a se arate view of a corner piece, showing a sllght modification of the. form illustrated in the other gures. Fig. 5 shows the sheet-metal piece employed to form, the tray illustrated.

As shown in the drawings, the bottom 2 and side walls 3, 3 of the tray are formed from' a single piece of sheet metal of rectangular shape; thecorners of said blank being cut away as shown so that the upturned edge portions forming the walls 3 have their meetingends 3a 3a slightly separated, instead of attempting t'o form a tight corner-,connection thereof. At each corner of this pan I provide an, angle-iron ycornerpiece, the angled anges orl arms 5, 5 of which are rigidly secured .to the adjacent meeting ends 3a 3a of the side walls, by livets 6 as shown. This corner piece has -its arms extended at one end above said side walls 3, such extensions 5a 5a being in the planes of the arms 5, 5, andA it is also extended at the other end, below the tray bottom 2, an off-set 5b beinghere formed however so as to throw the lowerarm extensions i Speoioatibn of Let'iei'i Htent. f Application med December v22', '1910. smal No. 598,951.

arms 5, 5 as shown, and thus provide an angular off-set-shoulder 5d; which shoulder is adapted to serve as a supporting seat for the opposite extensions 5a 5* of a mating `may extend either inward,`or outward (as indicated in Fig. 4;), to form this supporting -shoulder 5d inconnection with the guide extensions 5c 5; but when extended inward as indicated in Figs. 1, 2 and 3, so that the up, per shoulder' 5 of the off-set may seat a ainst the bottom of the tray as shown, this o -set serves the further purpose of assisting in the forming ofa tight .joint at the junction of the separated meeting ends 3 3a of the side walls'3, 3 of the tray, as provided for in the construction shown. This is accomplished by filling the small space naturally formed between the separated edges of these meeting ends 3a 3, with a suitable sealing material 10, which is supported uponsaid o-set and securely locked between the separated edges so as to form a permanently tight corner. As indicated in Fig. 2 these crner pieces provide for trays one upon another, with a determined spacing between the cnfections or other material placed thereon; the top extensions 5L 5a loosely engaging the off-set bottom extensions 5c 5c of a superposed tray and the angular shoulder 5d of the latter seating upon the ends of said extensions 5a 5a as shown; What I claim is 1. A tray having angularly arranged vertical walls, and exteriorly applied angleof which are attached intermediately yof their length tov adjacent meeting ends of said walls and have their opposite (ends extended respectively above and below said walls; the extended portions y,of the angledplates at one end being off-set to form anangular seating shoulder for the overlapping opposite extension of a meeting-tray corner piece, substantially as setforth.

2. A tray having a sheet metal bottom plate" having upturned edge-portions with separated umeeting ends; exteriorly applied angle-iron corner-pieces connecting said 5 5c into dl'erent planes, parallel with the tray asl hereafter described.
